Around $15–$20/month for a 20-30 slot server. For example, ScalaCube offers plans starting at $19 for 20 players. High-tier: Up to $45–$50/month for 100+ players. Key Features to Look For:
Rates typically depend on "slots" (maximum player count).
Public servers are frequent targets for attacks; good hosting includes this by default.
Choose a data center closest to your player base to minimize "rubber-banding" (lag).
